During a fundoscopic exam, small areas of dull, yellowish-white coloration in the retina are most consistent with which finding?

• A. Cotton wool spots
• B. Microaneurysms
• C. Hemorrhages
• D. Exudates

Answer: (A)

Dull, yellowish-white patches seen on the retina during a fundoscopic exam are cotton wool spots. These are microinfarcts of the retinal nerve fiber layer caused by ischemia, often associated with diabetic or hypertensive retinopathy. They appear as soft, fluffy pale patches and reflect localized nerve fiber damage from reduced blood flow. This distinguishes them from microaneurysms (tiny red spots from capillary wall outpouchings), hemorrhages (red to dark spots from blood leakage), and hard exudates (bright yellow lipid deposits with sharp margins).
